METHOD OF PRODUCING FORGED ARTICLES FROM SCRAPS OF METAL.

SPECIFICATION forming part of Letters Patent No. 397,278, dated February 5, 1889.

Application filed September 1 1, 1888- Serial No. 285,410. (No model.)

To (LZZ 1071,01 it may concern.-

Be it known that I,

EVANDER N. CoLwELL,

a citizen of the United States, residing at Allegheny, in the co unty of Allegheny and have invented certain a Method of Making Forgings with Dies; and I do hereby declare the following to be a full, clear, and

exact description of the invention such as will enable others skilled in the art to which it pertain being had which form a part of My invention relat s to make and use the same, reference to the accompanying drawings,

this speci fication.

es to a method for forming from wrought-iron or steel special shapes exact quantity desired forging, and,

of forgi female die to forging, and of accurate] weighing a suitabl heat, and by the dies converting solid mass, and at the sat sired shape of the for forth hereinafter.

In the accompanying drawing 3 is a side sectional elev used for the same pur ngs; and it consists in a male and form the desired shape of the y calculating and t e quantity of small scrap iron or steel, forming the same in a compact bundle, bringing this bun dle to a welding a proper fins and by the aid of l l l l l the said bundle into at ging, as will be fully set s, Figure 1 is male die such as I use for car-couplers. Fig. 2 base of the same. Fig.

ation of a female die pose, also showing a side elevation of the male die entered into the same. Fig. is a plan view of the female die. Fig. 5 is a perspective view 0 t a couplerhook such as produced by the above-descri bed dies.

To put my invent ion into practice, I provide a set. of dies, a I), having formed in the bot-tom of the female die (I, and on the base of the male die I), an impression su it-able for and corresponding withthe contour of the article to be formed. strueted so as to cont These dies 0 l) are conam a much larger body than that of the finished article.

In operation a calculation is made of the bundle of scrap having the desired w of metal required to form the when ascertained, a

or small pieces of iron eight, and firmly bound ne time form the dc- 1 jected to a heavy together, is provided.

. an iron bar, 0, is placed in a groove, (1, formed in the die a and allowed to project a short distance into the die a. The object of this bar 0 is to provide a simple means of lifting the finished article from the female die a. The said bar 0 becomes attached to the forging, and is afterward cut away from the same.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is Y 1. The herein-described method of forming forgings from wrought iron, steel, &c., consisting of placin a bundle of scrap or small pieces of iron into a female die, a, the said bun- 7'5 dle being at a welding heat, and subjecting the same to a pressure brought against a male die, b, whereby forgings from wrought-iron, wrought-steel, &c., may be formed.

2. The improvement in the art of making forgings of the class described, consisting in assembling small or scrap pieces of metal into a bundle, heating the bundle to a welding heat, placing the bundle within a female die constructed to give one part of the bundle the desired external contour, and finally forcing a male die upon the bundle within the female die, whereby the bundle is sub pressure and forged into a homogeneous body of the external contour 0 corresponding to the particular dies used, substantially as described.

In testimony that I claim the foregoing I hereunto affix my signature this 15th day of August, A D. 1888.

EVANDER N. COIAVELL.
